This was real FUN! For the first time in my 13 years life, I finally touched something that is COOL!
We were to find out the properties between a mixture and a compound. We learnt that sulpher and iron will become a mixture when mixed and when heated, a compound is formed. We were to use our past skills of observing and we observed sulpher powder. It is yellowish and powderish. We also found out that it could not be attracted to the magnet. After that we observed some iron fillings and found out that it was black, needle-like and that it ATTRACTED to the magnet. Next, we mixed the both items together and formed a mixture. It was yellowish and black and still powderish. Then we heated the two items together and formed a compound. The mixture melts and formed a black solid. The compound could not be attracted to the magnet. T.T! Then we discussed about some facts about the compound and mixture with our Science Teacher, Ms Leong and found out that the heat had distroyed some of the properties. Then we moved on to naming some new elements.
This lesson was by far the most fun lesson. We get to touch iron filling and sulpher, something I had not touched before. If I am not wrong, I think that sulpher is used to chase away snakes!?
